Preheat your oven to 350°F (175°C).
In a large mixing bowl, cream together the softened butter, brown sugar, and Sugar In The Raw until light and fluffy, about 3-4 minutes.
Add eggs, one at a time, mixing well after each addition, then stir in the vanilla extract.
Add the peanut butter and beat until smooth and creamy.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt, then gradually mix into the wet ingredients until just combined.
Scoop rounded balls of dough onto prepared baking sheets, sprinkle with turbinado sugar.
Bake for 10-12 minutes or until edges are lightly golden; let cool on baking sheets for 5 minutes before transferring to a cooling rack.
While cooling, melt chocolate in a microwave-safe bowl in 30-second intervals, stirring until smooth.
Dip half of each cookie into the melted chocolate, letting excess drip off, and place on parchment paper to set.
Once chocolate has set, enjoy your cookies!
